Conversion from Decimal to Hexadecimal
When converting from decimal to hexadecimal, we are essentially changing the base of the number system from 10 to 16. In decimal, we use ten digits (0-9), while in hexadecimal, we use sixteen digits (0-9 and A-F). Each digit in a hexadecimal number represents a power of 16, just like each digit in a decimal number represents a power of 10. For example, the decimal number 255 is equivalent to FF in hexadecimal because 255 = 15*16 + 15 = FF.
One relatable example of converting decimal to hexadecimal is when dealing with colors in web design. Colors on websites are often represented in hexadecimal format, where each color channel (red, green, blue) ranges from 0 to 255 in decimal. Converting these decimal RGB values to hexadecimal allows for easier coding and manipulation of colors in CSS. Another common use case is in cryptography, where hexadecimal is frequently used to represent binary data in a human-readable format.
